In this paper, we provide a comprehensive multivariate cointegration analysis of three parts of the steam coal value chain — export, transport and import prices. The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with...

Expenditures devoted to research and development (R&D) are scarce and thus need to be used as efficiently as possible given the financial constraints countries are facing. This paper assesses the relative efficiency of R&D expenditures for 26 OECD member countries and 2 non-member countries. As...

Efficiency measurement in public transport requires an adequate account of unobserved network characteristics that are typically modelled as factors separable from the production process. This paper proposes a panel data model that allows for non-separable firm-specific heterogeneity in an input...

In this paper, we provide a comprehensive multivariate cointegration analysis of three parts of the steam coal value chain - export, transport and import prices. The analysis is based on a rich dataset of international coal prices; in particular, we combine data on steam coal prices with freight...

On behalf of the Deutsche Telekom Stiftung (Deutsche Telekom Foundation) and the Bundesverband der Deutschen Industrien (Federation of German Industries) DIW Berlin has investigated Germany's innovative capacity for the fifth time in an international comparison. The survey evaluates the ability...

In this paper, we test the hypothesis that the economic transition toward a market economy increases the efficiency of firms. We study 32 Polish electricity distribution companies between 1997 and 2002, by applying common benchmarking methods to the panel: the non-parametric data envelopment...

We analyze the technical efficiency of German and Swiss urban public transport companies by means of SFA. In transport networks we might face different network structures or complexities, not observed, but influencing the production process. The unobserved factors are typically modeled as...

Die Lissabon-Agenda sieht eine Steigerung der Ausgaben für Forschung und Entwicklung bis zum Jahr 2010 auf drei Prozent des Bruttoinlandsprodukts vor. Europa will damit zu einem der wettbewerbsfähigsten und dynamischsten Wirtschaftsräume werden. Wesentlich für die Zukunftsfähigkeit eines...

Das DIW Berlin hat in diesem Jahr zum fünften Mal im Auftrag der Deutschen Telekom Stiftung und des Bundesverbandes der Deutschen Industrie (BDI) einen Gesamtindikator für die Innovationsfähigkeit Deutschlands im internationalen Vergleich ermittelt. Dabei wird die Fähigkeit eines Landes,...
